This part gloat and a question. I won a Clearvue DC on ebay, great price. It came with a good number of fittings. I know you use two 45’s instead of a 90 to make a turn, but how long a pipe in between the 45’s to make the turn? I have 12’ ceilings so I have some room.

You only need enough to connect the 2 =45s together. That expands the curve enough to prevent clogging.

I did some testing with 6” PVC last year, as I recall a 2’ segment between 45s came pretty close to the same performance as wide-sweep elbow. Two 45s butted back to back wasn’t as good, but far far better than a plain 90-degree elbow.

cr1 yeah your right there’s always money involved some where. I have read Bill Pentz info and i don’t think there was any length stated. TheWoodNerd the 2’ is that exposed pipe in between the fittings? Thanks guys for the help.

You can do the two 45° elbow method or you could simply us long turn 90° elbows. Regular 90° elbows won’t give you the gradual turn you need for the dust and air flow but LT 90°’s will. Cheaper than buying two 45’s too.

Whoa, where are you getting long-turn elbows for less than two 45s? As I recall, two 45s were about $9, whilst a long 90 was about $30.

You can get LT 90’s at most any plumbing wholesale house. Prices will vary but generally the wholesale houses are less expensive than the big box stores, Woodcrafts and Rocklers. It also depends on the type and size of piping you’re using. Sewer pipe and fittings should generally be less expensive than Sch 40 DWV pipe and fittings.
